Ever want a little light but can't find a flashlight or a battery? Here's how to solve that problem.

Steps

1

Gather the supplies needed for construction.

2

Cut the foil into circles the size of the quarter.

3

Cut the blotting paper into circles bigger than the foil or coin.

4

Dissolve and mix the 2 tablespoons salt into the vinegar.

5

Use the masking tape to attach the end of one of the wires to the underside of a foil disk.

6

Next, stack in the following order: foil, paper, coin, foil, paper coin. Each foil/paper/coin combination is a tiny battery, yet it will take quite a few of these to light even an LED (light-emitting diode).

7

Place one wire on the topmost quarter, which will be the positive terminal and bottom of the battery, the aluminum foil, which will be the negative terminal.
